Title: Enclosed type compressor
Inventor: SANO KIYOSHI
IPC: F04B39/12
Filed: 1982-03-17
Abstract: PURPOSE:To aim at securing a sufficient noise damping effect with an arbitray form of a case that shows no sharp resonance characteristic, by forming the hermetically sealed case of a compressor into a layer-built construction consisting of overlapped cylindrical cases. CONSTITUTION:When a compressor is operated, vibrations produced in a compressor part 2 are transmitted to a hermetically sealed case 1 via junction parts 5a-5c between the compressor part 2 and the hermetically sealed case 1 but, since the hermetically sealed case 1 is made up of a threefold shell comprising an outer shell 1a, an intermediate shell 1b and an inner wall shell 1c, it does not show any resonance characteristic at the specified frequency. Yet even to the vibration spread from the compressor part 2, vibrational energy is converted into thermal energy by dint of a relative motion produced in mutual relations among individual shells 1a-1c composed of the same material so that the further promotion of reduction in the vibration is much expected.

Title: Polisher for ultrapure water making apparatus
Inventor: HASHIMOTO NOBUKO
IPC: C02F1/42
Filed: 1990-02-23
Abstract: PURPOSE:To prevent the remaining of sterilizing chemicals in piping and to effectively prevent the deterioration of an ion exchange resin by providing a three-way valve to the branch part of water inflow main piping connected to a polisher inflow pipe. CONSTITUTION:A three-way valve 8 is provided to the branch part of main piping 1 connected to a polisher inflow pipe 7. In this polisher, the three-way valve 8 is changed over so that no chemicals flow in the branched inflow pipe 7 at the time of sterilization and sterilizing chemicals flow out through the three-way valve 8, bypass piping 4 and a three-way valve 6. By this method, since there is no liquid stagnation part, no sterilizing chemicals remain in the piping and washing is well performed after chemical sterization and, therefore, the deterioration of an ion exchange resin can be effectively prevented.

Filed: 1978-04-14
Abstract: PURPOSE: To enable distinct data images to be formed on a film without taking space by providing a self-focusing light guide material between a light source panel and film.  
     CONSTITUTION: A heterogeneous light guide material or self-focusing light guide material, e.g., self-focusing light guide material 18 is disposed between a printing light source panel 14 and a film 16.

Title: Bipolar photosensitive body
Inventor: UEDA HIDEAKI
IPC: G03G5/043
Filed: 1994-03-15
Abstract: PURPOSE:To improve the photosensitive body characteristic such as sensitivity and sensitivity balance and the follow-up ability when the static charge characteristics are switched by selecting an org. charge generating matrial contained in the first and second photosensitive layers from a combination of the n-type and p-type charge generating materials. CONSTITUTION:A first photosensitive layer 2 and a second photosensitive layer 3 are successively laminated on a conductive substrate 1. An n-type charge generating material is used in the layer 3 when a p-type charge generating material is used in the layer 2, and a p-type charge generating material is used in the layer 3 when the n-type material is used in the layer 2. The content of the material in the layer 3 is controlled to 1.2-20wt.%, based on the total constituting material of the layer 3. Consequently, a good balance in sensitivity is obtained between both poles, and the sensitive body is used as one with both positive and negative polarities. Further, the layer 2 effectively acts as a blocking layer to block the injection of a charge from the substrate 1, hence the rising of electrification is improved when the positive polarity is switched to the negative polarity or vice versa, and the follow-up ability is improved.

Title: Optical information recording and reproducing device
Inventor: HONDA SHUICHI
IPC: G11B21/08
Filed: 1987-02-26
Abstract: PURPOSE:To reduce the weight of a carriage and to shorten accessing time by means of rapid seeking by shielding parallel beams projected obliquely in a seeking direction by a shielding plate fitted to the carriage and detecting a change in the quantity of light by a photodetector. CONSTITUTION:The shielding plate 20 is fitted to the side of the carriage 6 so that parallel beams projected from a light source obliquely to the carriage moving direction can be shielded. The parallel beams 21 shielded and varied by the shielding plate 20 are detected by the photosensor 4 fixed on a device base 3. Since the parallel beams 21 are completely shielded by the shielding plate 20 when the carriage is positioned on the innermost periphery, no light is received by the sensor 4. Since the quantity of receiving light is changed in accordance with the movement of the carriage 6, the position of the carriage can be correctly detected by computing the output of the sensor 4. Thereby, a linear encoder is not required, so that the weight of the carriage can be reduced and rapid seeking can be attained.
